The number os sprays really depends on the fragrance. Some require more sprays while others are strong enough that a few sprays will do. There is no right or wrong answer. Just be wise not too overspray and test a fragrance out and the number of sprays that you feel are necesary before going into a room with many people. When I am in class I don't spray that much, but when I go out somewhere I spray more because I will not be enclosed in a small area with many people. The areas I spray are on my forearms and chest area. Since there is body hair there it will preserve the fragrance longer. I also put on a shirt after a minute or so since this will keep the fragrance around longer. The only thing I would probably advice against is spraying directly on your clothes since this will not allow the fragrance to develop like it would if it was sprayed on the skin.
